4-46 RSA3000E Programming Guide
Return Format
The query returns the reference frequency offset in scientific notation. The unit is Hz.
Example
The following command sets the reference frequency offset to 1 MHz.
:SENSe:DDEMod:FSK:DEViation:REFerence 1000000
The following query returns 1.000000000e+06.
:SENSe:DDEMod:FSK:DEViation:REFerence?
[:SENSe]:DDEMod:FSK:DEViation:REFerence:AUTO
Syntax
[:SENSe]:DDEMod:FSK:DEViation:REFerence:AUTO ON|OFF|1|0
[:SENSe]:DDEMod:FSK:DEViation:REFerence:AUTO?
